AMPLITUDE Y Scale
Point
Allows you to create or edit an 
amplitude-correction factor data point. 
Up to 200 points may be defined for 
each set. Enter the point number to be 
created or edited by using the numeric 
keypad, then press 
Enter, or use the 
knob, tab, or step keys to move to an 
existing point. Press 
Bk Sp to correct 
errors. After selecting a point, 
Frequency becomes active.

Frequency
Allows you to enter the frequency value 
for an amplitude-correction point. 
Enter the frequency value by using the 
numeric keypad. Change the frequency 
value by using the step keys or the 
knob. Press 
Bk Sp to correct errors. 
After selecting a point, 
Amplitude 
becomes active.
A frequency coordinate must always be 
specified for amplitude-correction 
factors.

NOTE The amplitude correction entered for the lowest frequency will be 
applied to all frequencies less than the lowest frequency entered. 
Similarly, the amplitude correction for the highest frequency entered 
will be applied to all frequencies greater than the highest frequency 
entered.
NOTE For amplitude-correction factors, a maximum of two entries with the 
same frequency are valid. Only the first and last points of a series with 
the same frequency values are used; any middle points are ignored. 
NOTE Amplitude-correction data is sorted in the table by frequency. The 
sorting occurs immediately after you have entered the frequency value 
via the front-panel.
